Ryuzo Yanagimachi
is a Japanese-born, American-based scientist. He has made numerous key contributions to the study of mammalian fertilization. He is a pioneer of assisted fertilization technologies such as in vitro fertilization and direct sperm injection into the egg (commonly called intracytoplasmic sperm injection or ICSI), which are widely used today in human infertility clinics throughout the world. He was also a pioneer in the cloning field. In 1997, his laboratory at the University of Hawaii at Manoa successfully cloned mice using the Honolulu technique. Early and later years Yanagimachi was born in Ebetsu and raised in Sapporo, Japan. He received a BS in zoology in 1952 and a DSc in animal embryology in 1960 both from Hokkaido University. Being unable to find a research position initially, he then worked as a high school teacher for two years. Yanagimachi applied for a post-doctoral position with Dr. M. C. Chang of the Worcester Foundation for Biomedical Research in Shrewsbury, Mass ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ebetsu, Hokkaido
is a city in Ishikari Subprefecture, Hokkaido, Japan. History Ebetsu was settled originally by Japanese people in 1871, who came from the Miyagi Prefecture on Honshu. In 1878, tondenhei began moving into the area. When the Meiji Government, in 1878, designated Hokkaido as part of Japan, settlers began to flood the area. Ebetsu earned township status in 1916 and city status in 1954. During the 1960s and 1970s, a burgeoning population in Sapporo caused the population in Ebetsu to concurrently boom. In 1991, the city reached 100,000 people. The name Ebetsu is derived from the Ainu name of the Chitose River which flows into the Ishikari River in the city. According to John Batchelor in his "An Ainu-English Dictionary" (chapter 1, section V: Place Names Considered) the Ainu language name was E-pet or "humour river" based on its murky colour. Demographics As of May 1, 2017, the city has an estimated population of 119,086, with 56,325 households, and a population density of 630 ...

Pluripotent Stem Cells
Pluripotency: These are the cells that can generate into any of the three Germ layers which imply Endodermal, Mesodermal, and Ectodermal cells except tissues like the placenta. According to Latin terms, Pluripotentia means the ability for many things. We can generate Induced Pluripotent cells by using the Induced pluripotency technique by triggering or expressing the genes or the transcription factors of the normal somatic cells. They are abbreviated as iPSC or IPS. We can forcefully express the transcription factors like Oct4, Sox2, Klf4, and c-Myc of a non-pluripotent cell and convert them into a stem cell. This procedure is first studied in a Mouse fibroblast cell in 2006 and followed the same instructions in developing a Human pluripotent cell from a Human epidermal fibroblast cell. The technique is called Regeneration. Though the iPSC has similar properties to embryonic stem cells they were never approved for clinical stage research because they are highly Tumerogenic, hav ...

In Vitro Fertilization
In vitro fertilisation (IVF) is a process of fertilisation where an egg is combined with sperm in vitro ("in glass"). The process involves monitoring and stimulating an individual's ovulatory process, removing an ovum or ova (egg or eggs) from their ovaries and letting sperm fertilise them in a culture medium in a laboratory. After the fertilised egg (zygote) undergoes embryo culture for 2–6 days, it is transferred by catheter into the uterus, with the intention of establishing a successful pregnancy. IVF is a type of assisted reproductive technology used for infertility treatment, gestational surrogacy, and, in combination with pre-implantation genetic testing, avoiding transmission of genetic conditions. A fertilised egg from a donor may implant into a surrogate's uterus, and the resulting child is genetically unrelated to the surrogate. Some countries have banned or otherwise regulate the availability of IVF treatment, giving rise to fertility tourism. Restrictions ...

Zona Pellucida
The zona pellucida (plural zonae pellucidae, also egg coat or pellucid zone) is a specialized extracellular matrix that surrounds the plasma membrane of mammalian oocytes. It is a vital constitutive part of the oocyte. The zona pellucida first appears in unilaminar primary oocytes. It is secreted by both the oocyte and the ovarian follicles. The zona pellucida is surrounded by the Corona radiata (embryology), corona radiata. The corona is composed of cells that care for the egg when it is emitted from the ovary. This structure binds spermatozoa, and is required to initiate the acrosome reaction. In the mouse (the best characterised mammalian system), the zona glycoprotein, ZP3, is responsible for sperm binding, adhering to proteins on the sperm plasma membrane. ZP3 is then involved in the induction of the acrosome reaction, whereby a spermatozoon releases the contents of the acrosome, acrosomal vesicle. The exact characterisation of what occurs in other species has become more ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Micropyle (zoology)
A micropyle is a pore in the membrane covering the ovum, through which a sperm enters. Micropyles are also found in sporozoites of some digenetic microorganisms such as ''Plasmodium'' at the anterior part of the cell that ultimately leads towards the apical cap. Examples of other organisms that have micropyles are the ''Bombyx mandarina'' and the ''Ceratitis capitata ''Ceratitis capitata'', commonly known as the Mediterranean fruit fly or medfly, is a yellow-and-brown fly native to sub-Saharan Africa. It has no near relatives in the Western Hemisphere and is considered to be one of the most destructive frui ...''. References Reproduction {{animal-anatomy-stub ...

Chemotaxis
Chemotaxis (from '' chemo-'' + ''taxis'') is the movement of an organism or entity in response to a chemical stimulus. Somatic cells, bacteria, and other single-cell or multicellular organisms direct their movements according to certain chemicals in their environment. This is important for bacteria to find food (e.g., glucose) by swimming toward the highest concentration of food molecules, or to flee from poisons (e.g., phenol). In multicellular organisms, chemotaxis is critical to early development (e.g., movement of sperm towards the egg during fertilization) and development (e.g., migration of neurons or lymphocytes) as well as in normal function and health (e.g., migration of leukocytes during injury or infection). In addition, it has been recognized that mechanisms that allow chemotaxis in animals can be subverted during cancer metastasis. The aberrant chemotaxis of leukocytes and lymphocytes also contribute to inflammatory diseases such as atherosclerosis, asthma, and arthr ...
